"The unconscious is the only available source of religious experience. This is certainly not to say what we call the "unconscious" is identical with God. . . or is set up in his place. It is simply the medium from which religious experience seems to flow. As to what the further cause of such experience might be, the answer to this lies beyond the range of human knowledge. Knowledge of God is a transcendental problem."
"The Undiscovered Self" - C Jung
Below is one of Carl Jung's visions. . .
"Suddenly it was as though the ground literally gave way beneath my feet, and I plunged down into the dark depths. I could not fend off a feeling of panic. But then, abruptly, at not too great a depth, I landed on my feet in a soft, sticky mass. I felt great relief, although I was apparently in complete darkness. After a while my eyes grew accustomed to the gloom, which was rather like a deep twilight. Before me was the entrance to a dark cave, in which stood a dwarf with leathery skin, as if he were mummified. I squeezed past him through the narrow entrance and waded knee deep through icy water to the other end of the cave where, on a projecting rock, I saw a glowing red crystal. I grasped the stone; I lifted it, and discovered a hollow underneath. At first I could make out nothing, but then I saw there was running water. In it a corpse floated by, a youth with blonde hair and a wound in the head. A gigantic black scarab followed him and then by a red, newborn sun, rising up out of the depths of the water. Dazzled by the light, I wanted to replace the stone upon the opening, but then a fluid welled out. It was blood. A thick jet of it leaped up, and I felt nauseated. It seemed to me that the blood continued to spurt for an unendurable long time. At last it ceased, and the vision came to an end." . . .
